Dissidia Thunder Crest is a ground magical Bravery attack for Mateus, learned at the start of the game. It requires 30 CP to equip (15 when mastered), 120 AP to master, is unblockable, and can absorb attacks. Mateus conjures a circle of lightning that paralyzes and damages the opponent if they are close enough.
Dissidia012 Thunder Crest returns as a Bravery attack for Mateus, now requiring 100 AP to master but is otherwise identical to its previous incarnation.
Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide).
